Description

Technical Field

[0001] This application relates to the field of gas meters, and particularly to wireless remote transmission diaphragm gas meters. Background Technology

[0002] The fuels people use for cooking have shifted from conventional energy sources like firewood and coal, which are wasteful and polluting, to cleaner energy sources like natural gas, coal gas, and even electricity. Gas meters have an automatic cumulative function, allowing households using natural gas or piped coal gas to easily track their consumption and pay their bills based on the monthly gas consumption in cubic meters. The gas meter's exterior only shows a small glass window displaying a digital dial with seven digits: the first four digits are black, and the last three are red.

[0003] Gas meters can leak due to aging internal components. When users are not home, the lack of a gas collection mechanism can lead to gas meter explosions. Furthermore, when staff check the gas usage, the dimly lit environment of the inspection well makes it difficult to see the gas meter readings clearly, and the display screen is often covered in dust, causing inconvenience to users.

[0004] Therefore, there is an urgent need for wireless remote transmission diaphragm gas meters. Summary of the Invention

[0005] The purpose of this application is to solve the problem of gas leakage inside current gas meters. Compared with existing technologies, it provides a wireless remote transmission diaphragm gas meter, including a gas meter body. A display screen is embedded on the outside of the gas meter body. A gas calculation device is installed inside the gas meter body. An inlet pipe and an outlet pipe are fixedly connected to the top of the gas meter body. The inlet pipe includes an inner pipe and an outer pipe. A pair of sealing rings are fixedly connected between the inner pipe and the outer pipe. A through hole located inside the gas meter body is opened at the outer end of the outer pipe. A protective cover is set at the outer end of the gas meter body. An air pump is fixedly connected to the inner top surface of the protective cover through a base. A negative pressure pipe is fixedly connected to one end of the air pump. One end of the negative pressure pipe extends between the inner and outer pipes. An internal pipe is fixedly connected to the other end of the air pump. An installation groove is opened inside the protective cover. The internal pipe is embedded in the installation groove. Multiple air bladders are fixedly connected to the inner wall of the protective cover. Multiple branch pipes are connected to the outer end of the internal pipe. The multiple branch pipes are interconnected with the cavities of the nearby air bladders. The meter body is equipped with a gas concentration sensor. Through a gas pump and solenoid valve, the gas concentration sensor detects any accidental gas spills in real time. Simultaneously, the gas pump absorbs the gas mixture inside the meter body and delivers it to the gas chamber. Since the gas chamber is filled with inert gas, it effectively dilutes the mixture, reducing the proportion of coal gas inside. At the same time, the gas mixture inside the meter body is extracted, allowing outside air to enter and further dilute any remaining gas. This effectively prevents the gas from reaching a certain ratio with oxygen, which could cause a gas explosion. Through the Internet of Things (IoT), gas leak information can be transmitted to the user's mobile phone, providing immediate alerts. Furthermore, pressing any part of the protective cover activates a touch switch connected to the controller, turning on the light and closing the solenoid valve. This activates the light and opens the dust cover, allowing users to easily view the gas meter readings.

[0006] Furthermore, a solenoid valve is fixedly connected inside the negative pressure pipe, one end of the gas concentration sensor is electrically connected to a controller, and one end of the controller is electrically connected to the gas pump and the solenoid valve.

[0007] Furthermore, multiple reset springs are fixedly connected between the periphery of the gas meter body and the inner wall of the protective cover, and touch switches are fixedly connected between the periphery of the gas meter body and the inner wall of the protective cover.

[0008] Furthermore, a light is fixedly connected to the top of the protective cover near the display screen, and multiple touch switches are electrically connected to the light.

[0009] Furthermore, one of the sealing rings is located above the negative pressure pipe, and the other sealing ring is located on one side of the through hole near the gas calculation device.

[0010] Furthermore, the inner top and bottom of the protective cover are fixedly connected with cushioning pads, and the air inlet and outlet pipes extend movably to the outside of the protective cover.

[0011] Furthermore, the airbag is made of elastic material and filled with inert gas, and the branch tube is equipped with a one-way valve.

[0012] Furthermore, a rectangular hole is provided on the outer side of the protective cover, and a rotating shaft is rotatably connected to the inner wall of the rectangular hole. A dustproof plate is fixedly connected to the outer wall of the rotating shaft.

[0013] Furthermore, a torsion spring is provided on the inner wall of the rectangular hole. The torsion spring is sleeved on the outside of the rotating shaft. One end of the torsion spring is fixedly connected to the dustproof plate, and the other end is fixedly connected to the inner wall of the rectangular hole. An electromagnet is fixedly connected to the inner wall of the rectangular hole.

[0014] Compared to existing technologies, the advantages of this application are: (1) By setting up an air pump and a solenoid valve, the gas concentration sensor is used to detect the gas that has been accidentally spilled in real time. At the same time, the air pump is turned on to absorb the mixed gas inside the gas meter body and deliver it to the gas bag. Since the gas bag is filled with inert gas, it can effectively dilute the mixed gas and reduce the content of coal gas inside the gas bag. At the same time, the mixed gas inside the gas meter body is extracted, and the outside air can enter the interior to further dilute the residual gas. This effectively avoids the problem of gas explosion caused by the gas and oxygen inside the gas meter body reaching a certain ratio. The gas leak information can be transmitted to the user's mobile phone through the Internet of Things, which can remind the user immediately. Moreover, when the staff presses the protective cover at any position, the touch switch can be connected to the controller, which will turn on the light and close the solenoid valve. The light will be turned on and the dust cover will be opened, making it convenient for the user to check the index.

[0015] (2) By setting up an airbag, when the gas concentration sensor detects a gas leak, the internal valves of the inlet and outlet pipes are closed immediately to prevent the gas from accumulating further inside the gas meter body. At the same time, the gas pump and solenoid valve are turned on. The gas pump starts to absorb the mixed gas inside the gas meter body through the through hole and delivers it to the airbag, thereby effectively avoiding the problem of gas explosion caused by the gas and oxygen inside the gas meter body reaching a certain ratio.

[0016] (3) Because the airbag is filled with inert gas, it can effectively dilute the mixed gas and reduce the proportion of coal gas in the air, thereby preventing coal gas explosion.

[0017] (4) When the protective cover is touched at any location, the lights near the display screen can be turned on by pressing the touch switch, which not only helps the staff with lighting, but also makes it easier to see the gas index on the display screen.

[0018] (5) Users can use the Internet of Things to display the gas-related index of the gas meter on the user's mobile phone in the background. When a gas leak occurs, the gas leak warning will be sent to the mobile phone through the Internet of Things as soon as possible to remind the user to take corresponding measures.

[0019] (6) The branch pipe is equipped with a waterproof and breathable valve. When the gas is introduced into the organic solvent, the methane inside the gas is dissolved, which also plays the role of collecting and treating the gas, effectively preventing the gas from spreading inside the gas meter body and causing an explosion.

[0020] (7) Since there is too much dust inside the inspection well, it is easy to block the display screen. It will need to be wiped by staff later. A movable dustproof plate can be set outside the display screen. When the protective cover is touched by external force, the touch switch will not only turn on the lighting through the controller, but also disconnect the electromagnet. The dustproof plate will rotate and spring open under the action of the torsion spring, exposing the display screen to the outside, making it convenient for staff or users to view.

[0021] (8) Because of the airbag, reset spring and buffer pad, when the staff or toolbox accidentally hits the gas meter body, the protective cover on the outside of the gas meter body will protect it. At the same time, the airbag, reset spring and buffer pad can also effectively buffer the external force, thereby protecting the gas meter body. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Example 1:

[0026] This application discloses a wireless remote-reading diaphragm gas meter; please refer to [link / reference]. Figure 1-4 The system includes a gas meter body 1, a display screen 3 embedded on the outside of the gas meter body 1, a gas calculation device inside the gas meter body 1, an inlet pipe 2 and an outlet pipe 13 fixedly connected to the top of the gas meter body 1, the inlet pipe 2 includes an inner pipe 21 and an outer pipe 22, a pair of sealing rings 23 fixedly connected between the inner pipe 21 and the outer pipe 22, a through hole located inside the gas meter body 1 at the outer end of the outer pipe 22, a protective cover 4 at the outer end of the gas meter body 1, a gas pump 6 fixedly connected to the inner top surface of the protective cover 4 through a base, a negative pressure pipe 7 fixedly connected to one end of the gas pump 6, and one end of the negative pressure pipe 7 extending between the inner pipe 21 and the outer pipe 22.

[0027] Please see Figure 6 The other end of the gas pump 6 is fixedly connected to the built-in pipe 8. The inside of the protective cover 4 is provided with an installation groove. The built-in pipe 8 is embedded in the installation groove. Multiple airbags 9 are fixedly connected to the inner wall of the protective cover 4. Multiple branch pipes 81 are connected to the outer end of the built-in pipe 8. The multiple branch pipes 81 are interconnected with the inner cavity of the airbags 9 nearby. A gas concentration sensor is installed inside the gas meter body 1.

[0028] A solenoid valve is fixedly connected inside the negative pressure pipe 7. One end of the gas concentration sensor is electrically connected to a controller, and one end of the controller is electrically connected to the gas pump 6 and the solenoid valve.

[0029] Please see Figure 5Gases mainly include natural gas, manufactured gas, liquefied petroleum gas, biogas, and coal gas. Taking household gas as an example, during operation: the gas concentration sensor detects in real time whether there is a gas leak inside the gas meter body 1. When a gas leak is detected, the internal valves of the inlet pipe 2 and the outlet pipe 13 are closed immediately to prevent the gas from accumulating further inside the gas meter body 1. At the same time, the gas pump 6 and the solenoid valve are turned on. The gas pump 6 begins to absorb the mixed gas inside the gas meter body 1 through the through hole and delivers the mixed gas to the gas bag 9 through the negative pressure pipe 7 and the built-in pipe 8, thereby effectively preventing the gas and oxygen from reaching a certain ratio and causing a gas explosion.

[0030] Please see Figure 7 The figure shows a block diagram of a gas absorption system. The gas concentration sensor detects the gas concentration and transmits the signal to the gas meter control unit (controller), which then activates the warning light, gas pump 6, and solenoid valve.

[0031] Multiple reset springs 5 ​​are fixedly connected between the periphery of the gas meter body 1 and the inner wall of the protective cover 4, and touch switches 11 are fixedly connected between the periphery of the gas meter body 1 and the inner wall of the protective cover 4.

[0032] A light 10 is fixedly connected to the top of the protective cover 4 near the display screen 3, and multiple touch switches 11 are electrically connected to the light 10.

[0033] Please see Figure 9 The figure shows a block diagram of a touch-sensitive lighting system. Since many gas meters are installed inside dimly lit inspection wells, it is very inconvenient to inspect or repair the gas meter body 1. Therefore, when the protective cover 4 is touched at any location, the light 10 near the display screen 3 can be turned on by pressing the touch switch 11. This not only helps the staff with lighting but also makes it easier to view the gas index on the display screen 3.

[0034] One of the sealing rings 23 is located above the negative pressure pipe 7, and the other sealing ring 23 is located on one side of the through hole near the gas calculation device.

[0035] The inner top and inner bottom of the protective cover 4 are fixedly connected with buffer pads 12, and the air inlet pipe 2 and the air outlet pipe 13 extend to the outside of the protective cover 4.

[0036] The top of the protective cover 4 has a movable hole. The outer diameter of the movable hole is larger than that of the inlet pipe 2 and the outlet pipe 13. The movable hole allows the gas meter body 1 to move slightly along with the inlet pipe 2 and the outlet pipe 13.

[0037] The airbag 9 is made of elastic material and filled with inert gas. The branch tube 81 is equipped with a one-way valve.

[0038] Because the airbag 9 contains inert gas, it can effectively dilute the mixed gas and reduce the proportion of coal gas in the air, thereby preventing coal gas explosions.

[0039] Please see Figure 8 The gas alarm system diagram shows that when users use it for the first time, they need to register and open an account with the gas company and pass on the barcode attached to the meter to the gas company. After payment, press and hold the function key of the meter for 3 seconds to enter the network mode. After successful network connection, the recharge will be credited to the account.

[0040] The meter uses an NB-IoT base station to communicate with the server. The communication process can be divided into five stages: initiating communication, searching for the network, connecting to the master station, data interaction, and communication termination.

[0041] Users can use the Internet of Things (IoT) to display gas-related indices from the gas meter itself on their mobile phones. In the event of a gas leak, an IoT alert will be sent to the user's phone immediately to remind them to take appropriate measures.

[0042] Example 2:

[0043] Please see Figure 10 This application discloses a wireless remote transmission diaphragm gas meter. The difference between Embodiment 3 and Embodiment 1 is that the following technical features are added: a rectangular hole 14 is provided on the outer side of the protective cover 4, a rotating shaft is rotatably connected to the inner wall of the rectangular hole 14, a dustproof plate 15 is fixedly connected to the outer wall of the rotating shaft, a torsion spring 17 is provided on the inner wall of the rectangular hole 14, the torsion spring 17 is sleeved on the outside of the rotating shaft, one end of the torsion spring 17 is fixedly connected to the dustproof plate 15, and the other end is fixedly connected to the inner wall of the rectangular hole 14. An electromagnet 16 is fixedly connected to the inner wall of the rectangular hole 14.

[0044] During operation, the dust inside the inspection well can easily obscure the display screen 3, requiring subsequent wiping by staff. A movable dustproof plate 15 can be installed outside the display screen 3. When an external force touches the protective cover 4, the touch switch 11 not only turns on the lighting 10 through the controller but also disconnects the electromagnet 16. The dustproof plate 15 rotates and springs open under the action of the torsion spring 17, exposing the display screen 3 to the outside for easy viewing by staff or users.

[0045] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
